Maybe twenty years ago, I remember my friend Harry, who knows a lot about cars, telling me about a magical idea called a “heads up display.” Harry explained that data and images would be projected on every car windshield, and if I understood him correctly, instrumentation would move from the dashboard to an ultra-simple visual presentation directly in the driver’s field of view. No more looking down, no more looking away from the road. I became vaguely aware that some truck drivers were using this technology, but I wondered whatever happened to the consumer side of the idea.

Next year, we can all buy a dashboard mounted video projector called a Navdy. It costs less than $30o, and it does what Harry promised, and more. Navdy projects very simple graphics and just a few words directly on the windshield, directly above the steering wheel. The projector is set up so that your point of focus on the data is also your point of focus while driving, so the information is always easy to see (I’m curious how those with bi- or trifocals will respond).

We all know that picking up a phone while driving (or stopped at a light) to read a text message is a bad idea, and that sending a text is an even worse idea. So now, the text shows up immediately in front of you, perhaps with a little iconic picture of your texting buddy (who is, hopefully, on a coach, not driving a big rig while texting). To reply, you either speak (Navdy will recognize what you have to say) or gesture (a favorite but simple way to interact with Navdy).

You can use your existing cell phone (Android or iPhone). There is no monthly service fee. You only need to buy the device.

So what else does Navdy do? It can display your fuel level, speed, and other information about your car. It allows you to make phone calls and to respond to them without touching a telephone. Ditto for text messages. If your phone is playing music, you can stop and start the stream. It responds to voice control, just as Siri does (hopefully, it’s better than Siri).

New idea? As an add-on, sure. But those who follow the car industry report several million HUDs (Heads-Up Displays) already in cars that are on the road, and have been for several years.

Although there are lots of questions about what we should and should not be doing while driving, whether Navdy is a help or a hindrance or something else entirely, whether this sort of thing will become standard in every vehicle, and, of course, whether most of us will actually be driving a car in a future where cars are probably going to be driving themselves. In the mean time—there’s at least a ten year gap between today and the future—this is a device that will become a buzz item in 2015.
